WELL-DRILLING MACHINERY.

SPECIFICATION forming part of Letters Patent No. 736,716, dated August18, 1903.

Application filed February 24, 1903. Serial No. 144,636. (No model.)

To (tZZ whom it may concern:

Be it known that I, Gnonon A. GILBORNE, of Aberdeen, county of Brown,State of South Dakota, have invented certain new and useful Improvementsin VVell-Drilling Machinery, of which the following is a specification.

My invention relates to machinery designed for use in drilling wells;and the object of the invention is to provide a compact portableapparatus that can be readily transported from place to place andconveniently set up and put in operation within a short space of timeafter being located where the work is to be done.

A further object is to provide an apparatus that is simple inconstruction and easily operated even by an inexperienced person.

A further object is to provide a machine that is self-contained, alloperating parts and power-generating means being included within thesingle structure, and hence more conveniently handled than othermachines usually used for the same purpose.

The invention consists generally in various constructions andcombinations, all as hereinafter described, and particularlypointed outin the claims.

In the accompanying drawings, forming part of this specification, Figure1 is a plan view of a well-drilling machine embodying my invention, theupper portion of the apparatus being cutaway, the supporting-timberstherefor being shown in section. Fig. 2 is a side elevation. Fig. 3 is aplan View. Fig. 4 is a detail of a belt-tightening mechanism. Fig. 5 isa detail, partially in section, of the device forimparting reciprocatingmovement to the drill and the reciprocating device over which the ropepasses to the drill. Fig. 6 is a detail of the worm-wheel and rod inmesh therewith. Figs. 7 and 8 are side and sectional views,respectively, of the disk shown in Fig. 5; and Fig. 9 is a detailshowing an adjustable pump-rod connection by means of which the pump maybe rendered operative or inoperative, as desired.

In the drawings, 2 represents parallel side timbers, supported on thewheeled axles 3 and 4: and connected at intervals by the cross timbersor bars 5. At the rear end of the frame are the uprightinwardly-inclined timbers 6, that form the lower section of thedrill-machine tower. These timbers are connected by the cross-slats 7 tothe upper ends of said timbers. A folding section 8 is hinged on a rod8. Bars 9 and 10 pivotally connect the middle portions of the timbers 7and the folded section 8. A pulley 11 is provided on the rod 8, and asimilar pulley 12 is provided at the outer end of the section 8. Whennot in use, the folding section is swung down against the timbers 6,Where it is suspended in a compact folded position until the machine hasbeen located near the work. It is then raised, as hereinafter described,to the position shown in dotted lines in Fig. 2, and suitable guy-ropes(not shown) are provided for staying and supporting the tower in itsupright position.

Near the middle of the machine I arrange a framework consisting of theposts or standards 13, resting upon the side timbers 2 and theintermediate timbers 14, and upon this framework I arrange a shaft 15,provided with a drum 16 and a worm gear-wheel17. A rope 18 is wound uponsaid drum and passes under a pulley 19, mounted in a forked bar 20, andfrom thence passes over the pulley 11 and is connected to the bars 9 ata point near their pivotal connection with the bars 10. (See Fig. 2.)The bar 20 is secured at its lower end to an arm 21, and at its upperend is connected to guide-bars 22, that are pivoted to the timbers 13and support the said bar 20 in an upright position, while permitting itsvertical movement. The arm 21 is mounted on a pin 23, carried by a crank24 on ashaft 25, that is mounted in hearings in the timbers 2 and 14.This shaft has a longitudinal movement in its bearings, being operatedby means of a pivoted lever 25, engaging a grooved collar 26, secured onsaid shaft. A projecting end 27 is provided on a pin 23, that is adaptedto enter a slot 28, provided in a disk 29 on a shaft 30, that is alsomounted in bearings in-the timbers 2 and 14 on the opposite side of themachine from the shaft 25. A block 30 is pivoted within the slot 28 andis normally held therein by a spring 31. Operation of the lever 25" willmove the shaft 25 lengthwise and advance the pin 27 into the slot 28against the block 30 and the tension of its spring. The operator willthus be able, when the disk 29 is revolving, to thrust the pin 27 intothe slot and cause the operation of the bar 20 without stopping themachine. An elliptical gear 32 is provided on the shaft 30, meshing witha similar gear 33 on a shaft 34, and through the operation of thesegears the disk 29 will be operated at a varying speed. A large gear 35is provided on the shaft 34, meshing with a pinion 36 on a shaft 37.Apulley 38 is connected by a belt 39 with a similar pulley on a shaft40, provided with fly-wheels 41, and said shaft 40 is connected with thepiston of an engine 42, mounted on the frame of the machine at itsforward end, and being of ordinary construction is not shown ordescribed in detail herein. The shaft 37 is preferably provided with afly-wheel 43. The opposite end of the shaft 34 from the gear 35 isprovided with a sprocket 44, connected to a similar sprocket on a shaftby belt 46. The shaft 45 is provided with a pulley 47, connected by abelt 48 with a pulley 49 on the shaft 15. This belt 48 is sufficientlyloose on the pulleys to allow movement of the shaft 45 without operatingthe shaft 15; but said shaft 15 may be operated from said belt bymovement of the belttightener 50, that is operated by means of the longarm 51, connected with the pivoted lever 52. The shaft 45 is provided atone end with a disk 53, whereon a hollow rod 54 is eccentricallymounted, and a stem 55 fits within said rod and is adjustably securedtherein by means of a set-screw 56. The outer end of said stem ispivotally connected with the piston-rod 57 of a pump 58, which is ofordinary construction, and not being claimed herein requires no detailillustration. The pump may be rendered inoperative at any time byloosening the set-screw 56 and allowing the stem' to slide thereinwithout operating the piston. I prefer to provide a friction-brakedevice on the shaft 15, consisting 'of a pulley 59 and a strap 60,secured at one end to the standard 13 and at its other to the pivotedlever 61, whose free end normally rests on a pin 62. Whenever desired,the operator can raise this lever off the pin and bearing down on thesame cause the strap 60 to grip the surface of the pulley and stop therevolution of the shaft 15 and the ropedrum.

Beneath the worm gear-wheel 17 I provide a rod 63, having anoperating-wheel 64 anda worm-gear 65, adapted to engage the teeth of theworm-wheel, and said rod is slidable in a bearing 66 to allow said gearto be moved into and out of engagement with the teeth of the worm-wheel,as indicated by full and dotted lines in Fig. 6.

The following is a brief description of the operation of my improvedwell-drilling machine: The apparatus having been set in the desiredposition where the work is to be performed, the tower is raised byunfolding the hinged sections. The rope is then disconnected from thebars 9 and passed over the pulley 12 and connected to the drill, asindicated by lease the belt and allow the shaft 34 to reciprocate thebar 20 without operating the shaft 15. This reciprocation of said barwill raise and lower the drill in the usual manner. As the hole isdrilled deeper and more rope is required the drum is unlocked andrevolved a few times until the desired amount of rope is obtained, whenit is again secured and the operation of drilling again continued.Whenever it is desired to discontin ue entirely the operation ofdrilling, the dru m-shaft will be revolved in the opposite direction,revolving the worm-wheel in the direction indicated by the arrow in Fig.6 and automatically throwing the worm 65 out of engagement with theteeth of the worm-wheel. The well having been completed, the operatorwill disconnect the rope from the drill, lower the upper section of thetower to its folded position, when the machine is ready to be moved toanother piece of work.

I claim as my invention- 1. The combination, with a wheeled frame, andthe tower provided thereon, of a ropedrum and shaft mounted on saidframe, means for operating said shaft, a shaft 30 connected with saidoperating means, a disk 29 secured on said shaft 30 and having a slot28, a block 30 yieldingly held within said slot, alongitudinally-movable shaft 25, a crank 24 carried thereby, a pin 27carried by said crank and arranged to enter said slot, a bar 20 carriedby said crank and provided with a pulley over which the rope passes fromsaid drum.
